Abstract excerpt
To investigate the improving effect of inter-chain disulfide formation on protein trans-splicing, we introduce a Cys point mutation at Tyr(664) in heavy chain and at Thr(1826) in light chain of B-domain-deleted FVIII (BDD-FVIII). By co-transfection of COS-7 cell with the two Cys mutated chain genes, the intracellular protein splicing, inter-chain disulfide formation, secreted BDD-FVIII and bioactivity in culture...
